No battery? Just got some lemons!

Do you know something about lemon chargers? Probably not, so it’s quite simple, bring some lemons connected together and they will produce some electricity, here we have pictures from iPod charging. You need a lot of lemons, a lot of lemons! The guy in this test is using 17 lemons (almost up to 4 volts, perfect for USB charging), they were barely enough to charge, but 20+ lemons will do it better 🙂 this is the best “ECO” or “Green” charger.

Warning – look at the polarity while connecting!  If you are not sure – check the multimeter data!
